The golden ratio is an irrational number that continues forever and is shortened to 1.618. The golden ratio is a mathematical rule that says any line can be divided so that the longer segment divided by the shorter segment is the same ratio as the full line divided by the longer segment. Greek mathematician Euclid was best known for his geometry work, now known as “Euclidian geometry.” He calculated the golden ratio using rectangles, which can also be explained using a line. The first recorded definition of the golden ratio came from Euclid in the 3rd Century BC. The golden ratio is a guide to where to place a subject (a tree, person, building, etc.) or element in a photo (like the horizon) where it will be most pleasing to the eye. ![]()
